Have you seen a full size car with 4 temporary spare tires on it. Tire sellers will let you have any stupid thing you want. LOL

The OP is mentioning the Pirelli AT Plus tires.You aren’t the only one that had that issue. I think I still have a set or two of new take off 275/55r20 Pirelli AT’s at work off of f150’s. They are not a good tire in the wet/snow/mud. They last a long time and are decently quiet, but compound is almost like hard plastic
Im running 40 PSIWhat air pressure in your tires?
I run mine at 30 PSI and they feel a lot better than when they were first installed and set at 40 PSI.Im running 40 PSI
I think the lesson here is the E Rating, and not the BFGATKO design. An E has a heavier carcass and stiffer plys. A Perelli Scorpion, Hankook, Bridgesstone Desert Dueller, or General Grabbers, if built to the same E Load rating would have similar drive characteristics when compared t lesser load rated tires.
I'm still going ATKO when I upgrade because I've had excellent results with them. But I'd never get an E Rated version
A C1 rated ATKO weighs in at 46LBS and runs on pavement at 40 PSI and carries a max load of 2469 per wheel for a combined axle load of about 5,000 LBS.
An E rated version weighs in 54LBS and runs on 80PSI on pavement and can carry up to 3197 per wheel for a combined axle load of 6,400 LBS
The Ford Published Max Rear Payload Capacity is 1,800 LBS. If you figure the back half of the truck doesn't weigh more than 1,000 LBS (just my guess) then the max load on your rear tires should never exceed 2,800 LBS. That's only 56% of what the C rated tires can handle and is a minuscule 43% of what the E rated tires can handle.
Since you are never likely to load up to a point that would make a critical difference betwen C and E rated tires, there is no beneficial trade off. You are sacrificing unsprung weight, rotational mass, stopping distance, fuel economy, ride comfort, and quite possibly a slightly noisier tire for no realizable benefit.
To the OP - See if you can go back to the dealer and make the case that a trained tire professional should have never let you put an E Rated tire on a Mid Sized Light Truck and that they steered you in the wrong direction at their own benefit for higher profit on a more expensive tire.
Put a set of cooper AT3’s on there. You will love them. It’s the best riding and driving AT tire out there and it’s not even close. Been in tire business for years and it’s hands down the best AT out there ride and drive quality wise. The BFG is one of the best looking tires out there but easily gets the most ride complaints. I run the Cooper 6 plys, wife has the 10 ply XLT’s and both are amazing.

I'll make the big decision tomorrow morning, the tune is next on my list, if that can improve my MPG and feel, i think i would keep these tires because they do look greatI replaced the stock Hankooks with Falken Wildpeaks and couldn't be happier. They are a little bit heavier and more aggressive, but flashing the (Ford) tune the same day gave me the impression of running faster and cleaner rather than slowing things down. I had Pirelli Scorpions on a previous vehicle (Explorer) and loved them, so you can't go wrong there either.
I decided to keep them, i like how tough they are but i did find positive camber, im having them fix the alignment today, we'll see if anything improvesI have these on my ranger, kinda felt sluggish as well until I got it aligned. Been good after that.
